Furthermore, the front panel of the air duct shell is provided with an air inlet, an interlayer is arranged at the position of the rear panel and communicated with the air duct through part, and the air exhaust fan is arranged at the interlayer and supplies air outwards.
Furthermore, the air exhaust fan exhausts air into the air duct main body, and air flow enters the air duct main body from the air inlet and is discharged from the air exhaust fan.
Furthermore, heat dissipation comb teeth are arranged in the rectangular air cavity part and the through air channel part.
Furthermore, the length of the radiating comb teeth penetrating through the air duct portion gradually increases from two sides to the center.
Furthermore, a through hole communicated with the interlayer is formed in the center of the through air duct part.
Compared with the background technology, the invention has the following advantages:
1, a low-noise double-fan system is selected to replace a single high-power fan with equivalent output air quantity, so that the air noise is reduced as much as possible.
2 the air duct of the case is optimally designed by the measures of streamline design of the air duct of the case, slope design of the air inlet of the air duct, design of the air inlet and the air outlet into an open large air port, design of a dust screen at the air inlet and the like, so that the wind resistance is reduced, and the noise caused by air flow is effectively reduced.

FIG. 1 is a schematic view of a duct system according to the present invention.
FIG. 2 is a side view of the air duct system of the present invention.
FIG. 3 is a top view of the air duct system of the present invention.
The air duct part 2, the rectangular air chamber part 3, the heat source 4, the upper cover plate 5, the lower cover plate 6, the air inlet 7 and the air outlet 8 are communicated.
Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
the noise control method of the system case during air cooling CPCI comprises the steps of reducing the noise of the whole case and reducing the noise pollution through a plurality of measures such as fan noise control, air channel optimization resistance reduction design, low-power-consumption module optimization and the like.
The design points of the invention are divided into the following parts:
1 when the method is implemented, the involved elements comprise: the air duct part 2, the rectangular air chamber part 3, the heat source 4, the upper cover plate 5, the lower cover plate 6, the air inlet 7 and the air outlet 8 are communicated.
The 2 CPCI case fan is arranged on the rear panel of the case, and heat dissipation is achieved through the form of air draft from the front to the back. When the air quantity requirement of the case is relative, a fan with low noise is selected; meanwhile, in order to further reduce wind noise, a single fan is changed into a double-fan system, and according to the same noise superposition formula, under the condition of not considering attenuation, the superposed noise of the two fans is N1+10log(N1) Compared with a single fan providing the same air quantity, the noise can be greatly reduced.
3 the air duct of the case is positioned between the CPCI card-inserting type box body and the upper cover plate and the lower cover plate, when the air duct is designed, the air duct is optimized by adopting corresponding measures, the air duct resistance is reduced, and the wind noise is reduced, wherein ① adopts a streamline design to avoid the air duct from turning sharply and expanding and contracting suddenly, the air duct resistance is reduced, ② the air inlet of the air duct adopts a slope design to reduce the airflow resistance, ③ the air inlet and the air outlet are designed into open large air openings to reduce the pneumatic noise generated during the ventilation of the inlet and the outlet, and ④ a dustproof net is designed at the air inlet to prevent dust from blocking the air duct, so that the wind resistance is increased.
4 the noise corresponding to different rotating speeds of the fan is different, and the larger the rotating speed is, the larger the noise is. When the case is designed, the use of the high-power-consumption modules is reduced as much as possible, because the high-power-consumption modules can release a large amount of heat when working, the rotating speed of the fan needs to be increased for preventing heat accumulation, and redundant heat is conducted out in time, so that the noise of the fan is increased. In order to suppress such negative effects, low power consumption devices and modules are preferable, and the heat dissipation amount of the chassis, the rotation speed of the fan, and noise are reduced.
